Description

Technical field

The invention belongs to the technical field of cable de-icing, and in particular relates to a cable de-icing device and a de-icing method.

Background technique

In the cold winter, overhead power lines are often covered with ice. Ice coating on transmission lines will affect the normal operation of the power system. In serious cases, it will directly lead to the disconnection of transmission lines and the collapse of towers, causing large-scale power outages and huge economic losses. Therefore, timely de-icing must be carried out.

At present, manual de-icing is mainly carried out by throwing ropes, friction or hammering with sticks, which is not only inefficient, heavy workload, poor de-icing effect, but also dangerous. Especially in the mountainous areas of Guizhou, power lines are erected along the mountains and across canyons and deep ditches. Manual de-icing is very difficult and the personal safety of workers cannot be guaranteed.

There are also methods that use alternating current or direct current for ice melting, that is, using alternating current or direct current to heat ice-covered cables for deicing. However, this method consumes large amounts of energy and equipment costs, and the ice and snow covering the circuit is generally thicker. In order to remove the ice on the cable, To remove all the ice and snow on the cable, it takes a long time to heat the cable. Cables are mostly made of rubber. Long-term heating will accelerate the aging of the cable and will inevitably affect the service life of the cable.
